STRIPPING MECHANl-SM FOR CARDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 430,200, dated June 17, 1890. Application filed July 10, 1889. Serial No. 317,089. (No model.)

To all whom it may concern:

Be it known that I, JAMES THOMSON, Jr., of IVillimantic, in the county of Windham and State of Connecticut, have invented certain new and useful Improvements in Stripping Mechanism for Carding-Machines, of which the following isa full, clear, and exact description, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide a device which, used in a carding-machine,will more effectually clean the carding-surfaces; and it is particularly adapted for use on a carding-machine in which the card-clothing is borne on traveling` iiats, as in the type of machine shown in United States patent to Leigh, of February 9, 1886, No. 335,760, although it is also adapted for use on the present type of cylinder that is covered with cardclothing.

My invent-ion consists in the combination of the card-clothed cylinder or like part, the reciprocating` comb, and the clearer or collector roll held in contact with the card-clothing by yielding pressure and adapted to be struck by the teeth of the comb in its reciprocation; and it further consists in details of the several parts making up the apparatus as a whole, and in their combination, as more particularly hereinafter described, and pointed out in the claims.

Referring to the drawings, Figure l is a side view of the traveling card-clothing, reciprocating comb, and the collector-roll. Fig. 2 is a front view showing the relative arrangement of the same parts.

In the accompanying drawings only so m uch of a carding-machine has been shown as is necessary to the understanding of the object of my invention and its relation to the apparatus as a whole, and in said drawings the letter a denotes the path of movement of the working-face of a cylinder or a series of traveling card-clothed tops or iiats.

h denotes the cardclothing; c, the comb supported on the comb-lever c and connected to the mechanism of the card in the usual manner, whereby the intermittent reciprocating movement of the comb along the face of the card-clothing is obtained. On the lever as by means of a belt c5, passing over the pulley c6, fastto the shaft. This construction of the comb-operating mechanism is a common one and Well known in the arts.

The letter d denotes the clearer or collector roll supported on the roller-supporting levers e, that are pivoted to opposite sides of the frame of the machine. These levers have, preferably, forked ends e', that being the most convenient form of bearing for the axes of the roller to permit the ready removal or insertion of a roller. A weight f is suspended from the arm e2 of each lever e in such manner as to hold the collector-roll d with a yielding pressure against the clothing on the card tops that are borne on the cylinder. weight f is made adjustable along the arm c2 of the lever, so as to readily change the degree of this yielding pressure. It is evident that a spring may be substituted for the weight as a means of producing this yielding pressure, but the weight is preferred, as being more positive in operation and more readily adj ustable.

In the operation of the machine the collector-roll, which is preferably of wood, is seated in the bearings in the levers and with its surface in position to be encountered by the card- The t teeth, by the contact with which the roller is cont-act of the comb with the mass of the waste material on the collector-roll. In fact, the movement of the latter is intermittent, and is aided by the contact of the comb With the mass of material. The comb has its usual function as acleaning device; but its efficacy is greatly increased by the use of the collectorroll, so that a new carding-machine, or one newly dressed, is thoroughly clean ed by the IOO operation of the collector-roll and the comb at once as soon as the machine is put in operation.

I claim as my invention- 1. In a carding-machine, in combination,

with the traveling card-clothing, the reciprocating comb, the collector-roll located in the path of movement of the comb, and the means, substantially as described, whereby the said roll is held with its surface in yielding contact with the card-clothing, all substantially as set forth, and for the purpose specified.

2. In a carding-machine, in combination with the traveling card-clothing, the recipro- JAMES THOMSON, JR.
